Cells located in distal regions of the primitive streak contribute first to the left ventricle (mid-streak stage), then to the right ventricle (late-streak stage), and finally to the outflow tract (OB-EB stages). Although the outflow and atria leave the primitive streak at similar stages, they arise from different regions. The outflow tract originates from distal locations in the primitive streak while atrial progenitors are positioned more proximally.
